There are some that would say gold prospectors plunder the environment. Well my wife and I just recently spent 6 days dry camping with 50 plus fellow RVers prospecting for gold. I am happy to report that they are conservationists while in the field. Estimates vary, but the US government calculates that each person in the country uses about 80-100 gallons of water per day. With the average RV having a capacity 40-50 gallons of water, and in this case two people per RV, that works out to 3 to 4 gallons per person per day. That is a savings of four to five hundred gallons per person over 6 days. I should also note that some soap was saved by some of the prospectors too, but that is just part of the adventure!
